Weights

Weights are essential tools in any environment to make sure testing performance accurate. Calibrating weighing devices or simply keeping equipment in place during extensive processing, the weights are specifically designed to meet international standards. Individual models needed or economical kits are constructed of durable metals to withstand heavy routine use and potentially harsh solvents encountered. The large style and size selection guarantees compatibility with existing equipment in the laboratory or classroom.
